alt Hacker NewsRed/green has no inherent semantics. It has the semantics that you assign it. If you choose to assign it meaning that disenfranchises 8% of men using your system, that's your choice, but it is not a good one.

Cultural semantics (diff tools, build tools,…: green/addition/ok, red/removal/error). And people with color blindness can alter the colors to something they can differentiate. And in the ansi sequences, they are actually numbers.
The standard terminal palette is only 16 colors. Even if you compress them all into the green-to-blue color range, it's still possible to distinguish all 16. The user can change "red" and "green" to whatever they like in the terminal preferences and then every 16-color app will be accessible with no additional effort from anybody.
